One interesting data point from this so far...and I should have realized this as it was under my nose. Jay Jones, the Virginia AG candidate was a dumpster fire full of loaded diapers and still won this past year. The rising tide is going to pull a lot of similar shaky (to be very generous) candidates over the line. I think Platner being younger and not Susan Collins will mean more than him being really shaky.
And before you dazzle me with your knowledge of how much money Collins will spend or electioneering the GOP will pull off... They threw the kitchen sink at Jones because it was the only election they thought they could win.
